python - openerp Message_post 错误..NameError : global name '_' is not defined

Question

我在表单中创建了一个带有聊天功能的自定义模块。

我想发布自定义消息。但我收到以下错误。

File "/opt/openerp/my_modules/forum/forum.py", line 22, in function_which_post_msg
    self.message_post(cr, uid, ids, body=_("New Question has been <b>created</b>"), context=context)
NameError: global name '_' is not defined

我的 .py 文件是

import datetime
import time
import openerp
from openerp.osv import osv, fields


class Course(osv.osv):
    _name = "forum.course"
    _inherit = ['mail.thread', 'ir.needaction_mixin']

    _columns = {
              'name' : fields.char(string="Question Title", size=256, required=True),
              'description' : fields.text(string="Question Description", required=True),

               }


    def function_which_post_msg(self, cr, uid, ids, context=None):
        self.message_post(cr, uid, ids, body=_("New Question has been <b>created</b>"), context=context)

    def create(self, cr, uid, ids, context=None):
        self.function_which_post_msg(cr, uid, ids, context=context)

尝试将其导入您的 .py 文件

来自 openerp 导入工具

从 openerp.tools.translate 导入 _

_ 用于在事件用户的语言根据更改时翻译消息。它翻译您的 .po 文件中的消息。
